Dr. Alexander Wunsch believes that everyone should know the truth about the potential way in which LED’s could be harming your eyes. Near-infared light is damaging to the eyes as it is taken in as radiation.

Wunsch explains:

“Here you have only very low absorption by water molecules, and this is the reason why radiation has a very high transmittance,” and “In other words, it penetrates very deeply into your tissue, so the energy distributes in a large tissue volume. This near-infrared A is not heating up the tissue so you will not feel directly any effect of heat.

“This significantly changes when we increase the wavelength, let’s say, to 2,000 nm. Here we are in the infrared-B range and this already is felt as heat. And from 3,000 nm on to the longer wavelength, we have almost full absorption, mainly by the water molecule, and this is [felt as] heating.”

Radiation exposure to our eyes in the way that near-infared light penetrates them leaves them unable to repair their cells in the way they would normally.

To help reduce the risk of radiation exposure in this way, try and get as much of your light from natural sources.

Wunsch goes on the explain the severe damage that can be done to your bosy from radiation light sources, saying:

“The radiation can enter your body and then be transformed into longer wavelengths in the infrared part. They are very important for supporting the temperature level, the thermal energy level, of our body which is … a very crucial aspect. A lot of energy comes in the form of radiation and this is supporting our thermal balance,”
